The report presents preliminary results on fatigue of wood subjected to tension perpendicular to the grain at a moisture content around 12% and 17%. The main result of the paper concerns the frequency dependency of the fatigue strength. At present it is concluded that fatigue in tension perpendicular to the grain can be time dependent as well as time independent depending on stress level and moisture content.
